10 Claims.

This invention relates to a beam hanger whereby .the operating end of the beam is coupled to the polished rod for the purpose of pumping-a well.

"An object of my invention is to provide a beam hanger which has a straight lift and in which the reins are coupled to the head by a universal connection.

,,:Another object is to provide a beam hanger of the, character stated, in which the head is attached to the blocks on the beam in a simple and novel manner. I w r I A feature of my invention resides in the novel universal 'joint in the lower end of the head, so

. that astraight lift is accomplished, and further in the novel back brace which is attached to the head, and thirdly, the novel oiling arrangement for the universal coupling. v

Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detailed description and the appended claims.

In the drawings: Figure 1 is a side elevation of my hanger as mounted on a beam.

lower portion of which is broken away to show interior construction.

Figure 9 is a top plan view of the same.

Figure 10 is a longitudinal, sectional view of the back brace mounting.

Figure 11 is a perspective view of one of the locking collars.

Referring more particularly to the drawings, the beam hanger l is supported from one end of the usual beam 2. The hanger includes a head 3 which is preferably supported on the beam 2 in the following manner: A shaft 4 extends through an eye 5 adjacent the upper end of the head. A pair of blocks 6-6 are fixedly mounted on the top of the beam 2 and are slotted to receive the shaft 4.

The shaft 4 is held against upward movement shell which is preferably integrally formed 10 the head. Theshell J ll is formed with, an arcuate bearing groove II in the bottom thereof. ;A trunnion bearing base l2 fits in the shell l0, and this baseis provided with an arcuate bearing shoe l 3" on the bottom thereof. I'he shoe I3 fits 1 in thegroove l l and thus a rocking motion is permitted in thefplane of the horizontal axis of th'e 'shell 1.0. 'P i -To prevent the, bearing base l2 from moving out ofthe shell I0, I provide a pair of outwardly 20 extending pins. l 4l4 on the trunnion base. These 'pins extend into recesses [5 in the shell, thereby preventing the bearing base from accidentally moving out of the shell when a load is applied to the beam hanger.

A metal liner I 6 -fits in the bearing base l2. Theliner is provided with oil grooves l and holes 18 in the bottom' thereof. The holes l8 permit oil to flow downwardly through the liner and o nto the inner face'of the bearing base l2. cap I9 is boltedon to the base l2, so as to enclose the trunnion 20. The outer ends of the trunnion .23 are hexagonal in shape and receive reins 2l-2I. The reins extend downwardly to the usual polished rod clamp, all of which is usual and wellknown in the art. :The central portion or 'thetrunnion 20 is enlarged'as shown in Figure 2, and when the cap i9 is bolted in position, the trunnion is held against endwise movement.

A tongue 22 is provided in the liner l 6, and this tongue extends into an angular groove in the trunnion, thus further aligning the trunnion in the bearing base.

A back brace 23 is pivotally attached to ears 24 of the head, and this back brace is fixedly attached to a bracket 25, which is secured to the beam 2.

A pair of hemispherical thrust buttons 23 screw onto the back brace 23, and these buttons bear against the front and rear faces respectively, of the bracket 25. The hemispherical shape of the buttons 26 permits the back brace 23 to extend in various vertical angles from the bracket 25 to the head 3, that is, this particular construction permits the back brace to be angularly adjusted to suit various conditions.

Having described my invention, I claim: 1. A beam hanger comprising a head, mounting means for the head on'a beam, a universal joint at the lower end of the head, a pair of reins,
